Hi ,
I am converting an GEF application to GMF application as a process of
learning , I am trying to reuse my old figures as much as possible, in doing
that am facing a small issue (prbly. dont know how to do ) -
The issue is ,
I have added a custom figure - mapping to my Old Figure - ,
1. the old figure has constructors which takes the various parms , how do i
set values of constructor using Custom Attribute Feature of the Custom
Figure ?
2. Is that possible to pass any other figure that exists in my GMFGraph as
an attribute to the Custom Figure?
e.g I have a label defined in my Gmf Graph and i want to pass that value
to the Custom Attribute
3. What does the Multistatement proeperties in the Custom Attribute is for
and how it can be used .
Is there any documentation that defines the GMF Graph figures and the
attribute that it denotes , what to pass etc.,
It will be great if some pointer are available to these or any suggestions.
Thanks,
Kamesh
